PRIMARY BATTERY.

Specification of Letters Patent.

Patented Feb. 153= 1906.

Original application led July 18, 1904, Serial No. 217,063. Divided and this application filed March 29,1905. Serial No. 252,783.

WOOD, residing inl New York city, borough oi" Manhattan, and GEORGE A. LUTZ, residing in N ew York city, borouh of Brooklyn, New

York, citizens of the United States, have in- -rented certain new and useful Improvements in Primary Batteries, of which the following is a specification.

This application is a division oi" our application, liled lluly 15, 1904, Serial No.217,063, for imprm'ements in primary ba teries, which has reference to using perforated retainers containing a depolarizer-such, for instance, as cupric oXid--with means to prevent the depolarizer from sifting through the perforations ol' the retainer during transportation and handling.

In carrying out our present invention we a ply a hinder to the wall oi' the retainer to cihse or fill the perforations in thel retainer, which binder is soluble in the liquid or solution used in the cell, and suchbmder so applied to the retainer prevents the particles of the depolarizer from passing through the apertures ol' the retainer', whereby retainers lmay be charged with depolarizer, shipped t 1 the place of use without loss of the depolarizer, and then the old retainermay be removed from' a cell and the new retainer inserted in its place, therehy overcoming the necessity of removing a retainer, cleaning out the reiuse depolnrizer, recharging the retainer with new depolarizer, and replacing the retainer in the cell.

Tile invention also comprises the novel details of improvenmnt that will be more fully hereinafter set forth and then pointed out in the. claims.

lhrference is to he had to the accomlmnying drawings, forming part hereof, wherein-:-

Figure l is a vertical section oi' a primary battery embodying ourinvention, part ofthe wall of the retainer being shown unbroken and covered with the hinder; and Fig. 2 is an enlarged detail sectional view ol the retainer.

ln the accompanying drawings, in which.

similar numerals of reference indicate corresponding parts in the views, the numeral l indicates the jar,'2 its cover, 3 the zinc, and 4 the binding-post connected with the retainer or cylinders for the depolarizer, all of which may he oi' usual construction. The retainer or holder we have shown iorfthe'depolarizcr or cupric oxid is in the form'if two perforated shells or cylinders 5 (i, one within the other,

the dcpolarizcr or cupric oxid being located in the space 7 between said cylinders, the ends of the s ace 7 being closed by covers 9 10, to which t 1e cylinders 5 6 are attached. The rod 11 is shown connecting the cover 9 with the binding-post 4, whereby the retainer is supported from cover 2. A hinder (indicated at 12) to retain the depolarizer within s ace 7 is applied to the cylinders .-5 6 so as to c ose the a ertures therein, and this may be done by fil ing said apertures with the hinder or by pasting the binder along the walls of the retainer, either inside oroutside, or both,

whereby the loose particles of the depolarizer will be retained within the space 7 and kept from passingv through the apertures during transportation and4 handling. The binder We use is such that is soluble in the liquid or solution used in the cell without materially affecting the electrical efficiency of the battery or cell, and for this purpose we may use sugar or similar saccharine matter, which when dissolved in the solution permits access of the solution to the depolarizer in usual manner.

The retainers provided with the binder closing the apertures and charged with the depolarizer, as set forth, areto be furnished ready Jfor use, so that when a cell is to be recharged with depolarizer it will be merely l necessary to remove the old retainer, which may be discarded, and apply a new retainer charged with the depolarizer, as stated, hy assing the rod 11 through it in and attach- Ing the rod to the binding-post 4. By charging the retainers and applying the binder at the factory in the manner stated they may he shipped without danger that the depolarizer willhe lost therefrom, and the loss ol' time and'annoyanee required in removing used-u p or exhausted depolarizer from retainers, cleaning out the retainers, and recharging the latter 'with depolarizcr is avoided.

While we have referred to the use of cuprie oxid as a depolarizer, it will he understood that our invention is not limited to the use oi such oxid', as any other well-known corresponding depolarizer may he used, according 4to the character ol' the battery.

solution appliedr to the wall ofthe retainer' closing the periorations therein to prevent lOO such depolarizer from passing throu h the erforations in the retainer, said bin er bemg of a character to not materially affect' the electrical efiicienc'y ot the battery, vsubstan- A ing o1 a character to not materially affect the electrical eiiiciency of the battery, substantially as described.

3. A battery element comprising perforated shells disposed one within'another, providing a space closed at opposite ends, .a deolarizer Within said space, and a binder solu- A le in a battery liquid or solution applied along the Walls of said shells covering the perforations therein to prevent such depolarizer from passing through the perforations, said binder being of a character to not materially affect the electrical eliciency vof the battery,

substantially as described. I

4. In a battery, the combinationsof a liquid-holding jar, a perforated retainertherein containing a depolarizer, a binder applied `to the wall of the retainer closing the Iperfoarizer rations therein to revent the depo from passing throug the perforations in the retainer, said binder being soluble in the batteryliquid or solution and of a character to not materially affect the electrical efliciency of the battery, and a negative element in the jar adjacent said retainer, substantially as 5 described.

5. In a battery, the combination of-a liquid-holding jar, a retainer therein having'inner and outer perforated Walls .providing a space, a de olarizer in said space, a binder applied to t e wallsof the retainer closing the erforations therein to revent the depolarizer from passing throng i the perforations in the retainer, said binder being soluble in the battery liquid or solution and of a character to not materially affect the efficiency of the battery, and a negative element in the jar adjacent said retainer, substantially as de scribed.

6. In a battery, the combination of a liquid-holding jar, a. perforated retainer therein, a depolarizer 1n the retainer,V a zinc between the retainer and the Wall of the -j ar, a

caustic solution in the jar, and a binder alppliedto the Wall of the retainer closing t e erforations therein, said binder being solu- Ele in said solution and of a character to not materially affect the electrical efficiency of the battery, substantially as described.
